2 tier acrh means that 5 IBM engineers have developed SAP R/3
sap means system application in product in data processing.r means real time
3 means architecture earlier all manuf company are using one tier R/1 in 1970s where all the activities are taken single software are department.which ever is the concern (for example take a paper and write single tier cycle there make 3 division on the single tier and put it as application,presentation,implementation.this exactly that tells all departments are running in one tier if any thing went wrong every thing will be courpted ,. the same system
they developed in 1980s called R/2 version.
that make a example of bicycle in one tier application were running at the same time,, another tier was presentation and implementation this done because to over cum from the errors
if error have encountered in application they can easliy find it out.
latter version 1990 is R/3 that three is having different tier for example auto rickshaw,.. i hope tht u ill understand this one
